Hey, wondering if any1 can help, I've got a S2 which is standard apart from chip. I've recently re-built engine and fitted new turbo and radiator. When starting it will wind and wind and eventually offer a few times and then after about 2 mins will finally start( and yeah I've tried disconnecting cold start). When started I've to keep revs up til warm or will cut out. Seems awful misfirey and when driving it just splutters. It runs to hot aswell(just below red). Im not convinced my coolant is bled?? Also the oil pressure light came on a few times, but only when accelerating. Can the fuelling effect the temp the car runs at?? I was thinking fuel pump relay or fuel ecu?????Also the exhaust downpipe flange is not sealing very well at turbo. Any help wud be appreciated. Cheers Gav.

 

sounds fucked, but u say u rebuilt it? did u do the head gasket properly?? and timin also firein order!!

 

Yip, im a mechanic to trade, but when it comes to Rs Turbos its a different story The head gasket was done proper and the firing order is pro.

 

Timing could be out,oil pressureswitch could be fooked,thermostat could be fooked and fan switch/fan.

 

Also I read on a post that the cold start valve has a blue connector, i always thought it was brown/tan colour?? Are they idiot proof because im sure I put the brown one on to it?

 

Yeah , could be oil press switch. New thermostat fitted and fan switch ok. I was thinking more air locks in coolant system. Wasn't sure the best way of bleeding them?

 

they are colour coded m8,blue is cold start can't remember what the brown and yellow one's are

 

i was told to take the pipe off the top of the thermostat housing to bleed the cooling system.

 

like he says m8 the connectors are idot prof, just connect colour to colour, but as i said b4 check the timin, ur oil pressure could be ur oil return pipe bein blocked!!

 

ive got a very semailer problem with my s1 it runs shity untill she's warmed up its just been rebuilt so im going to hae the fueling looked at and see

 

Yip, im going 2 set the 'Co' at work tomorrow, hopefully I get sum improvements. I really need 2 get it set up.

 

check for air leaks as well m8 mines got a small one and its runnig rough but does need setting up on the rollers
